The bacterial diversity of the bioaerosol from swine manure
composting was evaluated by DGGE analysis of the amplified
partial 16S rDNA genes, in which each band corresponded to
approximately one dominant microbial community. The closest
affiliation along with percentage identity data of the bands based
on the sequences is shown in Table 2. Four major bacterial taxa
were identified, of which nine sequences were related to the class
Bacteria, five were affiliated with Firmicutes, four were related to
Proteobacteria, and two to Actinobacteria. This observation indicates
microbial diversity of bioaerosols, i.e., the presence of various
species in the exhaust gas. In the raw sample of the swine manure,
the most abundant species were bacteria (65%), whereas other species
were c-proteobacteria (35%).
